Edwardian Platinum, Sapphire & Diamond Oval Cluster Ring

241 Admirers

A really beautiful sapphire and diamond oval cluster ring that was made circa 1900-1915. The sapphire is a stunning Royal blue colour and is most likely of Burma origin. It has millgrain detail around it. This is when the edges of the metal have been worked with a knurling tool to produce tiny beads, hence the French name “Millgrain” meaning a thousand beads. It is surrounded by well matched white diamonds. The shank is platinum. It sits low on the finger so it is a really practical ring to wear, and would be an amazing engagement ring.
